Data Analysis Strategies
Concepts in Research Design
Quantitative Designs
Representativeness of Sample
Sampling Method
100
Constant Comparison
What is defined as categories elicited from the data and compared with data obtained earlier in the data collection process so that commonalities and variations can be determined
100
What is causality
When things are said to have causes that lead to effects
100
What is Descriptive Design
This type of study does not involve any manipulation of variables and is meant to gain a clearer picture of the phenomenon before causality can be established
100
What is random variation
This refers to measurement values within a sample that may vary without direction; being lower or higher than the average of the population
100
This is when the researcher knows some of the variables he wishes to study in the population that are critical for achieving representativeness and uses:
What is Stratified random sampling
200
What is Coding
The process of reading data, breaking text down into sub-parts, and giving a label to that part of the text
200
What is Probability
When causation is relative rather than absolute
200
What is Quasi-experimental
This study does not use control groups but instead uses comparison groups
200
The difference between the sample and the mean is seen in the same direction rather than variably
What is systematic variation
200
Utilizes several stages of sampling in an effort to link multiple elements of the identified population
What is cluster sampling
300
Hermeneutic Circle
Textual analysis emphasizes the social and historic influences on qualitative interpretation and exposes hidden meanings
300
What is Control
A study of preoperative teaching in which subjects are randomly selected and then randomly assigned to the experimental or control group is also known as
300
What is Experimental Design
This type of design focuses on examining causality possessing both a control and experimental group
300
If you have 10 of 100 potential subjects consenting to participate in the study the amount would be ___ and is referring to the _________ rate.
What is acceptance rate and 10%
300
This is also known as accidental sampling or taking individuals because they are in the right place at the right time
What is Convenience Sampling
400
What is reflexive thought
Dynamic interaction occurs between the researcher and his or her experience of the data, whether the data are communicated orally or in writing
400
What is Manipulated
In a study of the effects of preoperative teaching, one group of subjects receives pre-operative teaching and another did not; in this care pre-operative teaching is being:
400
What is Correlational Design
The purpose of this type of study examines relationships among variables but does not attempt to control or manipulate the situation
400
This refers to the number of withdraws or loss of subjects from a research study; So if you had a total of 130 subjects and 31 subjects withdrew) what would be your _____ rate
What is attrition rate; approx. 24%
400
This strategy ensures that underrepresented groups will be included in the sample or essentially replicating the proportions of subgroups present in the target population
What is Quota Sampling
500
What is descriptive statistics
Quantitative analysis of data used to describe the characteristics of the population such as mean, median and age of the population
500
What is Bias
This factor distorts the findings from what the resuts would have been without it
500
What is Case Study Design
This design usually involves a small amount of subjects but studies many variables within a single unit
500
The number of subjects who remain in the study; so if you have 175 subjects enter the study and only 25 who complete it your ________ rate is ?
What is Retention Rate: 14%
500
This is a form of _______ sampling that is often used with sensitive data and takes advantage of social networks and the fact that friends tend to have characteristics in common and is known as:
What is Network sampling or snowball sampling
